Détermination des vitesses de glissement lors de l'écoulement d'une suspension non newtonienne par utilisation de la vélocimétrie ultrasonore à effet Doppler

Abstract

The study of two-phase flows, such as liquid-solid suspensions, requires the development of adequate experimental tools. They must allow the determination of both velocity distributions for the two species mixed together. The use of the ultrasound velocimeter will provide us with the possibility of determining both fluid particles and solid suspension velocities.
